click on image to call javascript of pup up calendar, why the form submit?

[michelle Wang]

I have a image of calendar on a JSP page, and the page is in a struts form.
When i click on the calendar, it should display a calendar to choose DOB, but now when the calendar pop up, the form also been submited, wondering how to prevent this?

If your image is being displayed as an input field (i.e. <input type="image"> , then it will submit the form when it is clicked. Otherwise you should be using the javascript onClick or html's href for the anchor tag around the image.
